Effect of environmental intervention on mouse allergen levels in homes of inner-city Boston children with asthma.

BACKGROUND: Recent studies have suggested that mouse allergen exposure and sensitization are common in urban children with asthma. The effectiveness of environmental intervention in reducing mouse allergen exposure has not been established. OBJECTIVE: To evaluate whether environmental intervention of mouse extermination and cleaning results in a reduction in mouse allergen levels. METHODS: Eighteen homes of children with positive mouse allergen skin test results and at least mild persistent asthma in urban Boston, MA, with evidence of mouse infestation or exposure were randomized in a 2:1 ratio (12 intervention and 6 control homes). The intervention homes received an integrated pest management intervention, which consisted of filling holes with copper mesh, vacuuming and cleaning, and using low-toxicity pesticides and traps. Dust samples were collected and analyzed for major mouse allergen (Mus m 1) and cockroach allergen (Bla g 1) at baseline and 1, 3, and 5 months after the intervention was started and compared with control homes. RESULTS: Mouse allergen levels were significantly decreased compared with control homes by the end of the intervention period at month 5 in the kitchen and bedroom (kitchen intervention, 78.8% reduction; control, 319% increase; P = .02; bedroom intervention, 77.3% reduction; control, 358% increase; P < .01; and living room intervention, 67.6% reduction; control, 32% reduction; P = .07). CONCLUSIONS: Mouse allergen levels were significantly reduced during a 5-month period using an integrated pest management intervention.

Impact of an intervention to improve treatment-seeking behavior and prevent sexually transmitted diseases among Nigerian youths.

BACKGROUND: Interventions to treat STDs have been reported to reduce HIV incidence. Interventions to improve treatment-seeking for STDs may impact on the duration and prevalence of STDs. Nigeria has high rates of STDs and an increasing incidence of HIV. OBJECTIVE: To evaluate the impact of an intervention on STD treatment-seeking behavior and STD prevalence among Nigerian youth. METHODS: A randomized controlled trial in 12 schools in Edo State was conducted to evaluate an intervention to improve STD treatment-seeking and STD treatment provision. The intervention, based on formative research, consisted of community participation, peer education, public lectures, health clubs in the schools, and training of STD treatment providers, including those with no formal training. A questionnaire measured outcomes before and 10 months into the intervention. The effect of the intervention among four randomly selected intervention schools compared to eight randomly selected control schools was assessed using logistic regression with Huber's formula to account for school clusters. RESULTS: One thousand eight hundred and ninety-six and 1858 youths 14-20 years of age were enrolled in the pre- and post-intervention surveys. Youths in the intervention schools, compared to control schools, reported statistically significant improvements in knowledge of STDs, condom use, partner awareness that the youth had an STD, and STD treatment-seeking behavior. Treatment by private physicians increased (OR=2.1, 95% CI=1.1-4.0), and treatment by patent medicine dealers or pharmacists decreased (OR=0.44, 95% CI=0.22-0.88). The reported prevalence of STD symptoms in the past 6 months was significantly reduced in the intervention compared to control schools (OR=0.68, 95% CI=0.48-0.95). CONCLUSION: Significant improvements in treatment-seeking for STD symptoms can be effected among Nigerian youths. The prevalence of reported STD symptoms can be decreased by improving treatment-seeking for and awareness of STDs.

Self reported clinical pharmacist interventions under-estimate their input to patient care.

OBJECTIVE: Pharmacists' impact on individual patient care is difficult to measure especially the contribution made by clinical pharmacy ward visits. This study set out to determine what activities pharmacists actually undertook on a clinical pharmacy ward visit and compare this with the usual method of measuring clinical pharmacist performance, self-reported pharmacist interventions. METHOD: Observational analysis was carried out on 16 pharmacists providing a ward clinical pharmacy service in four acute hospitals. MAIN OUTCOME MEASURE: Percentage of pharmacist interventions recorded. RESULTS: A total of 34 wards were visited during the study which included both medical and surgical specialties. Average time spent per patient was less than two minutes for most pharmacists and three-quarters of the pharmacists checked over 80% of patient drug charts. Interventions represented 68% of pharmacist activities on the wards but on questioning the pharmacists reported that they would record only 31% of those interventions. Comparison of the interventions the pharmacists stated they would record with an historical sample of recorded interventions from the four hospitals showed a similar pattern in each intervention category. However, pharmacists were more likely to record interaction type interventions and less likely to record interventions on incomplete/illegal prescriptions, which were regarded as routine practice. CONCLUSION: Pharmacists reported they would record less than one-third of interventions observed. If recorded pharmacist interventions continue to be used the main source of evidence of outputs of clinical pharmacy service, a better way of capturing this data needs to be developed.

Nutrient intakes and cholesterol values of the parents in a prospective randomized child-targeted coronary heart disease risk factor intervention trial--the STRIP project.

OBJECTIVE: To analyze food consumption, nutrient intakes and serum cholesterol concentrations of the parents in a child-targeted CHD intervention trial, during which the age of children increased from 7 months to 5 y. DESIGN AND SUBJECTS: The children were randomized to an intervention group (n = 540) or a control group (n = 522) at six months of age. The intervention families were counseled at 3-6 month intervals to reduce their child's intake of saturated fat and cholesterol. Dietary issues were discussed with the control families only briefly. The parents' food consumption was analyzed by 24 h dietary recall at the child's age of 7 and 13 months and at 2, 3, 4, and 5 y. Nutrient intakes were calculated using the Micro-Nutrica program. RESULTS: The mothers and fathers of the intervention children used less butter, more margarine and more skim milk than those of the control children (P < 0.001 for all measurements). After the onset of counseling, the intervention mothers consumed continuously less fat (1.4 E% less at the child's age of 5 y), less saturated fat (1.5 E% less at the child's age of 5 y) and more polyunsaturated fat (0.5 E% more at the child's age of 5 y) than the control mothers (P = 0.008, P < 0.001 and P < 0.001 for trend, respectively). After the child's age of 13 months the intervention fathers also had a continuously lower fat intake (2.4 E% less at the child's age of 5 y) and consumed less saturated fat (1.5 E% less at the child's age of 5 y) than the control fathers (P < 0.001 for trend for both measurements). The serum cholesterol concentration of the intervention mothers was consistently lower than that of the control mothers during the intervention (at child's age of 5 y 4.86 and 5.09 mmol/L, respectively; P for trend = 0.03), while the values of the intervention and control fathers showed no differences. CONCLUSIONS: Continuous dietary intervention begun in infancy and focused on modification of the child's diet according to the current principles of preventive cardiology, was accompanied by a moderate decrease in the intake of total and saturated fat in the parents, but serum cholesterol concentration diminished consistently only in the mothers of the intervention children.

Glaucoma case finding: a cluster-randomised intervention trial.

PURPOSE: To assess the effect of an intervention comprising training in optic disc assessment, explicit referral criteria and ophthalmologist feedback on referred patients, on the number of optometrist referrals for suspected glaucoma seen at a referral site and the positive predictive value of those referrals. METHODS: Optometric practices routinely referring to the Ealing Hospital Eye Clinic were randomly divided into two groups taking into consideration those practices, which shared an optometrist (a cluster) and the number of optometrist days worked per week. One group of practices acted as controls, while the other practices were invited to receive the intervention. Data on 397 new patients referred and presenting to Ealing Hospital with suspected glaucoma were collected over a 20-month period. The data on patients who had failed to attend their appointment were collected over 7 months of this period. The number of referrals seen, the positive predictive value of those referrals, and the attendance rate were calculated. Optometrist's opinions of the intervention were assessed qualitatively. Data relating to optometrist compliance with the intervention were also collected. RESULTS: The number of glaucoma referrals presenting to Ealing Hospital from the intervention practices was almost double that from the control practices (210 vs 119). When cluster randomisation, the number of optometrist days per cluster and the number of assessed referrals in the preintervention period are taken into consideration, it is estimated that the intervention is associated with a 52% increase in the number of referrals reaching Ealing Hospital. However, the design effect resulting from the cluster randomisation was unexpectedly high (of the order of 13-14)and so the confidence intervals around the estimate of 52% are very wide (95% c.i. 35% decrease to 253% increase, P = 0.34). There was no evidence of an association between optometrist compliance with the intervention and the number of referrals seen at Ealing Hospital. The positive predictive value (PPV)of referrals was similar for the intervention(0.49 (95% c.i. 0.42, 0.55)) and control groups(0.46 (95% c.i. 0.33, 0.60)). Optometrist opinions of the intervention were largely favourable. All expressed a willingness to participate in future programmes. CONCLUSION: A large difference in the number of referrals between the practice groups was observed. Since the PPV of referral was unchanged, the potential impact of the intervention in terms of numbers of new cases of glaucoma detected in the community is substantial. However, because of its large design effect, this trial does not provide conclusive evidence of an impact of the intervention on referral numbers. A considerably larger trial will be required to produce conclusive evidence of an effect.

Interventions to prevent weight gain: a systematic review of psychological models and behaviour change methods.

OBJECTIVE: To identify and review published interventions aimed at the prevention of weight gain. DESIGN: A systematic review of published interventions aimed at the prevention of weight gain. METHODS: Search strategies-we searched eight databases, manually checked reference lists and contacted authors. Inclusion and exclusion criteria-studies of any design, in which participants were selected regardless of weight or age, were included. Interventions targeting a specific subgroup, multifactorial interventions, interventions aimed at weight loss, and those with an ambiguous aim were excluded. Data extraction-data were extracted on behaviours targeted for change, psychological model, behaviour change methods and modes of delivery, methodological quality, characteristics of participants, and outcomes related to body weight and self-reported diet and physical activity. Classification and validation-a taxonomy of behaviour change programmes was developed and used for classification of underlying model, behaviour change methods, and modes of delivery. The data extraction and subsequent classification were independently validated. RESULTS: Eleven publications were included, describing five distinct interventions in schools and four in the wider community. Where diet and physical activity were described, positive effects were usually obtained, but all were measured by self-report. Effects on weight were mixed but follow-up was generally short. Smaller effects on weight gain were found among low-income participants, students and smokers. Many participants in the community-based studies were overweight or obese. Study dropout was higher among thinner and lower-income subjects. CONCLUSION: Interventions to prevent weight gain exhibited various degrees of effectiveness. Definite statements about the elements of the interventions that were associated with increased effect size cannot be made as only one of the five studies that involved an RCT design reported a significant effect on weight. This intervention involved a correspondence programme and a mix of behaviour change methods including goal setting, self-monitoring and contingencies. Future interventions might be more effective if they were explicitly based on methods of behaviour change that have been shown to work in other contexts. Effective interventions would be more easily replicated if they were explicitly described. Effectiveness might be more precisely demonstrated if more objective measures of physical activity and diet were used, and if the follow-up was over a longer period.

Randomized controlled trial of brief cognitive-behavioural interventions among regular users of amphetamine.

AIMS: To identify whether brief cognitive-behavioural interventions are feasible among regular users of amphetamine, to assess the effectiveness of intervention overall and to pilot two- and four-session interventions. DESIGN: Subjects were assigned randomly to individually receive a cognitive-behavioural intervention (n = 32) of either two or four sessions' duration or a self-help booklet (control condition; n = 32). SETTING: Subjects were volunteers recruited from needle exchange schemes and treatment centres in Newcastle, Australia. PARTICIPANTS: Regular (at least monthly) users of amphetamine were recruited. INTERVENTION: Either four sessions of cognitive-behaviour therapy, consisting of a motivational interview and skills training in avoidance of high-risk situations, coping with craving and relapse prevention, or two sessions consisting of a motivational interview and discussion of skills. MEASUREMENTS: The Opiate Treatment Index was the main measure at pre-treatment and 6-month follow-up. FINDINGS: There was a significant reduction in amphetamine use among the sample as a whole, with inconclusive differences between intervention subgroups. There was a moderate overall intervention effect, with the intervention group reporting over twice the reduction in daily amphetamine use as the control group. Significantly more people in the cognitive-behavioural intervention condition abstained from amphetamine at 6-month follow-up compared to the control condition. CONCLUSION: Brief cognitive-behavioural interventions appear feasible among regular users of amphetamine. A larger randomised controlled trial of the effectiveness of such interventions appears warranted.

A method to develop a nursing intervention: the contribution of qualitative studies to the process.

AIM OF THE PAPER: To describe how to develop a patient-centred nursing intervention (NI). BACKGROUND: The stimulus for scrutinizing methods and techniques to develop a NI was a research project concerning the contribution of information and support to the sexual adaptation of women with gynaecological cancer. Within this project, a NI for sexual teaching (ST) was developed because the literature review revealed no tested NI for this purpose. How patients experience and perceive received information influences the usefulness and efficacy of a teaching intervention. Qualitative methods provide insight and understanding of patients' experience. Consequently, qualitative methods are appropriate to use when developing interventions that aim to influence patients' situations through the provision of information. METHOD: Previously reported approaches for developing an intervention did not match the goals and underlying premises identified for the intervention under development. An alternative method, consisting of a design phase and a testing phase, was developed. The goal of the design phase was to develop a working definition of the intervention and to formulate recommendations for carrying out the intervention. Written guidelines provided concrete examples of the topics to discuss and how to discuss them. During the design phase, a qualitative study was conducted to describe the lived-experience of the phenomenon that the information should influence, namely sexuality after treatment for gynaecological cancer. In the testing phase, a different type of qualitative study took place. The patients' experience of receiving information and the nurses' experience of providing it were investigated in order to refine the proposed intervention, to identify the results patients hope to achieve (or achieved) and to explore the underlying theoretical explanation of the intervention. During the testing phase, the feasibility and acceptability of the modified intervention were both established. CONCLUSION: Even when the starting point is advice from care-givers, an intervention can be developed that is in harmony with the patient perspective when qualitative studies are part of the process.

Meta-analysis of randomized control trials addressing brief interventions in heavy alcohol drinkers.

OBJECTIVE: To assess the effectiveness of brief interventions in heavy drinkers by analyzing the outcome data and methodologic quality. DESIGN: (1) Qualitative analysis of randomized control trials (RCTs) using criteria from Chalmers' scoring system; (2) calculating and combining odds ratios (ORs) of RCTs using the One-Step (Peto) and the Mantel-Haenszel methods. STUDY SELECTION AND ANALYSIS: A MEDLINE and PsycLIT search identified RCTs testing brief interventions in heavy alcohol drinkers. Brief interventions were less than 1 hour and incorporated simple motivational counseling techniques much like outpatient smoking cessation programs. By a single-reviewer, nonblinded format, eligible studies were selected for adult subjects, sample sizes greater than 30, a randomized control design, and incorporation of brief alcohol interventions. Methodologic quality was assessed using an established scoring system developed by Chalmers and colleagues. Outcome data were combined by the One-Step (Peto) method; confidence limits and chi 2 test for heterogeneity were calculated. RESULTS: Twelve RCTs met all inclusion criteria, with an average quality score of 0.49 + or - 0.17. This was comparable to published average scores in other areas of research (0.42 + or - 0.16). Outcome data from RCTs were pooled, and a combined OR was close to 2 (1.91; 95% confidence interval 1.61-2.27) in favor of brief alcohol interventions over no intervention. This was consistent across gender, intensity of intervention, type of clinical setting, and higher-quality clinical trials. CONCLUSIONS: Heavy drinkers who received a brief intervention were twice as likely to moderate their drinking 6 to 12 months after an intervention when compared with heavy drinkers who received no intervention. Brief intervention is a low-cost, effective preventive measure for heavy drinkers in outpatient settings.

Effectiveness of a skin cancer control educational intervention for internal medicine housestaff and attending physicians.

OBJECTIVES: To evaluate the effects of a brief educational program on beliefs, knowledge, and behaviors related to skin cancer control among internal medicine housestaff and attending physicians. DESIGN: Randomised controlled trial. SETTING: Urban academic general medicine practice. PARTICIPANTS: Internal medicine housestaff and attending physicians with continuity clinics at the practice site. INTERVENTION: Two 1-hour educational seminars on skin cancer control conducted jointly by a general internist and a dermatologist. MEASUREMENTS AND MAIN RESULTS: Self-reported attitudes and beliefs about skin cancer control, ability to identify and make treatment decisions on 18 skin lesions, and knowledge of skin cancer risk factors were measured by a questionnaire before and after the teaching intervention. Exit surveys of patients at moderate to high risk of skin cancer were conducted 1 month before and 1 month after the intervention to measure physician skin cancer control practices reported by patients. Eighty-two physicians completed baseline questionnaires and were enrolled in the study, 46 in the intervention group and 36 in the control group. Twenty-five physicians attended both sessions, 11 attended one, and 10 attended neither. Postintervention, the percentage of physicians feeling adequately trained increased from 35% to 47% in the control group (p = .34) and from 37% to 57% in the intervention group (p = .06). Intervention physicians had an absolute mean improvement in their risk factor identification score of 6.7%, while control physicians' mean score was unchanged (p = .06). Intervention and control physicians had similar increases in their postintervention lesion identification and management scores. Postintervention, the mean proportion of patients per physician stating they were advised to watch their moles increased more among intervention physicians than control physicians (absolute difference of 19% vs -8%, p = .04). Other changes in behavior were not significant. CONCLUSIONS: Although we observed a few modest intervention effects, overall this brief skin cancer education intervention did not significantly affect primary care physicians' skin cancer control attitudes, beliefs, knowledge, or behaviors. A more intensive intervention with greater participation may be necessary to show a stronger impact on attitudes and knowledge about skin cancer control among primary care physicians.

A review of the effectiveness of agriculture interventions in improving nutrition outcomes.

OBJECTIVES: To review the impact of agriculture interventions on nutritional status in participating households, and to analyse the characteristics of interventions that improved nutrition outcomes. DESIGN: We identified and reviewed reports describing 30 agriculture interventions that measured impact on nutritional status. The interventions reviewed included home gardening, livestock, mixed garden and livestock, cash cropping, and irrigation. We examined the reports for the scientific quality of the research design and treatment of the data. We also assessed whether the projects invested in five types of 'capital' (physical, natural, financial, human and social) as defined in the Sustainable Livelihoods Framework, a conceptual map of major factors that affect people's livelihoods. RESULTS: Most agriculture interventions increased food production, but did not necessarily improve nutrition or health within participating households. Nutrition was improved in 11 of 13 home gardening interventions, and in 11 of 17 other types of intervention. Of the 19 interventions that had a positive effect on nutrition, 14 of them invested in four or five types of capital in addition to the agriculture intervention. Of the nine interventions that had a negative or no effect on nutrition, only one invested in four or five types of capital. CONCLUSIONS: Those agriculture interventions that invested broadly in different types of capital were more likely to improve nutrition outcomes. Those projects which invested in human capital (especially nutrition education and consideration of gender issues), and other types of capital, had a greater likelihood of effecting positive nutritional change, but such investment is neither sufficient nor always necessary to effect change.

Smoking cessation interventions for in-patients: a selective review with recommendations for hospital-based health professionals.

A selective review of the literature was conducted to provide evidence-based recommendations for the clinical management of hospitalized smokers. The Cochrane library, in particular the Cochrane review of 'Interventions for smoking cessation in hospitalised patients', was the basis for the review and was supplemented with other clinical and non-clinical literature where the review did not inform clinicians sufficiently. Evidence was reviewed on issues considered by the authors to be of importance to health professionals interested in providing a smoking cessation intervention to their patients. The review suggests that effective hospital interventions: incorporate an in-patient intervention lasting greater than 20 minutes in duration with extended post discharge follow-up; consist of at least five intervention contacts; and be delivered over at least a 3-month period. Furthermore, interventions should include in-patient advice and counselling, the provision of nicotine replacement therapy and extended proactive post discharge telephone support. The review also indicates that cessation interventions are particularly effective when delivered to patients with a cardiovascular diagnosis. All health professionals may be effective in providing cessation treatments; however, the addition of a specialist smoking cessation counsellor appears to improve interventions in this setting. Finally, without the development of supportive systems, routine intervention with smoking patients by health professionals is unlikely. Recommendations for the delivery of effective smoking cessation interventions in hospitals are provided. [Wolfenden L, Campbell E, Walsh RA, Wiggers J.

An STD/HIV prevention intervention framework.

Historically, interventions to prevent STD/HIV transmission have been categorized by program methodology rather than defining the content and nature of the intervention. A new taxonomy is needed to help expand the scope of interventions that can be used to prevent STD and HIV transmission. The taxonomy defines two major types of interventions, individual-level and structural level. The former targets risk factors attributable to individuals. Structural interventions target conditions outside the control of the individual. Individual-level interventions focus on counseling, screening, and treatment. They include psychological and biological interventions. Structural-level interventions address accessibility of relevant consumer products (condoms, needles), physical structures (e.g. blighted and abandoned housing, lighting, design of social facilities), social structures (policies that facilitate or constrain behaviors such as supervision of youth, and enforcement of alcohol beverage laws); and media messages (messages and images in the broadcast and print media that portray high-risk behaviors as positive and without serious consequences). A new taxonomy not only clarifies the content of preventive interventions but highlights neglected strategies involving individual biological interventions and structural interventions to prevent STD/HIV transmission.

Improving follow-up after an abnormal pap smear: results from a quasi-experimental intervention study.

The success of cervical cancer control programs depends on regular screening with the Pap smear test and prompt and appropriate treatment of early neoplastic lesions. Recognizing the potentially grave consequences of lack of follow-up for abnormal Pap smears, numerous intervention studies have tested the impact of a variety of strategies to increase return for follow-up. The majority of these studies were evaluated under controlled experimental conditions. Despite the encouraging findings of these trials, the next step in the research continuum requires that the effectiveness of these interventions be demonstrated in real world settings before full implementation is initiated. We report the results of an evaluation study assessing the combined effectiveness of three intervention modalities found effective in prior randomized studies: a tracking follow-up protocol, transportation incentives, and financial incentives. This study used a before-after, nonequivalent control group design to assess the impact of a multifaceted intervention that included a computerized tracking protocol with transportation and financial incentives. The study was implemented at two major hospitals, two comprehensive health centers (CHC), and nine public health centers (PHC) under the jurisdiction of the Los Angeles County Department of Health Services. One hospital, one CHC, and the four PHC located in the catchment area of the CHC were selected as experimental sites. The control sites - one hospital, one CHC, and five PHC - provided usual care. All women with an abnormal Pap smear at the intervention and control sites were included in the study. The study consisted of a 1-year period of baseline data collection (September 1989-August 1990), followed by a 2(1/2)-year intervention period (September 1990-February 1993). During the intervention period, the intervention protocol was implemented at the experimental sites, and the control sites provided usual care. Overall, we found that the rates of receipt of follow-up care were consistent with those found in similar studies. In contrast to results obtained in these prior randomized trials, we did not find strong and consistent evidence for intervention effects. Significant findings emerged only at the CHC and hospital levels and only for selected years. Results underscore the importance of testing interventions in real world conditions before large-scale implementation is initiated. In addition, this study highlights the challenge of detecting intervention effects in large-scale studies because of the greater measurement difficulties in field studies as compared with controlled experiments.

Community pharmacist interventions in a capitated pharmacy benefit contract.

Documented interventions associated with processing prescriptions in a managed care environment were analyzed, and a bench-mark for interventions was proposed. A retrospective analysis of documented interventions by 31 pharmacies contracted by a managed care organization to serve 22,000 Medi-Cal patients was undertaken. An intervention consisted of identifying any problem related to a prescription, taking action, and recording the problem, action, and outcome on a form. Problems were categorized as drug selection issues, clinical issues, errors in prescription writing, and patient education issues. A similar process was followed for describing actions and outcomes. The data were used as an indicator of prescription-related problems in contemporary pharmacies in a managed care environment; data from another study were used as an indicator of "ideal" pharmacist performance in detecting and resolving problems. The estimated intervention rate when pharmacists meeting ideal performance expectations worked in a managed care environment was set as a benchmark. The economic impact of drug selection interventions was determined as well. Data were retrieved and compiled from 595 (93.4%) of 637 interventions performed in 1995, when 93,483 contract-related prescriptions were processed by the 31 pharmacies. Fifty percent of problems related to drug selection issues. The most frequent action was contacting the presciber (56.1%). The overall intervention rate was 0.7% (range, 0-4.1%). It was estimated that 4% of prescriptions would require an intervention; two pharmacies met this level. Interventions resulting in prescription change realized an average decrease in cost of 65.8%. Community pharmacies under contract with a managed care organization intervened on 0.7% of prescriptions, but the rate of intervention across pharmacies was inconsistent, ranging from 0% to 4.1%; a benchmark of 4% would be reasonable.

Brief interventions for at-risk drinking: patient outcomes and cost-effectiveness in managed care organizations.

AIMS: Evaluate effectiveness and costs of brief interventions for patients screening positive for at-risk drinking in managed health care organizations (MCOs). METHODS: A pre-post, quasi-experimental, multi-site evaluation conducted at 15 clinic sites within five MCO settings. At-risk drinkers (N = 1329) received either: (i) brief intervention delivered by licensed practitioners; or (ii) brief intervention delivered by mid-level professional specialists (nurses); or (iii) usual care (comparison condition). Clinics were randomly assigned to three study conditions. Data were collected on the cost of screening and brief intervention. Follow-up interviews were conducted at 3 and 12 months. RESULTS: Participants in all three study conditions were drinking significantly less at 3-month follow-up, but the decline was significantly greater in the two intervention groups than in the control group. There were no significant differences between the two intervention conditions. Of the patients in the intervention conditions 60% reduced their alcohol consumption by > or =1 drink per week, compared with 53% of those in the control condition. No differences were found on a measure of the quality of life. Differential reductions in weekly alcohol consumption between intervention and control groups were significant at 12-month follow-up. Average incremental costs of the interventions were 4.16 US dollar per patient using licensed practitioners and 2.82 US dollar using mid-level specialists. CONCLUSION: Alcohol screening and brief intervention when implemented in managed care organizations produces modest, statistically significant reductions in at-risk drinking. Interventions delivered to a common protocol by mid-level specialists are as effective as those delivered by licensed practitioners at about two-thirds the cost.

How effective are interventions with caregivers? An updated meta-analysis.

PURPOSE: The purpose of this study was to determine the effectiveness of interventions for family caregivers of older adults. DESIGN AND METHODS: Meta-analysis was used to synthesize the effects of 78 caregiver intervention studies for six outcome variables and six types of interventions. RESULTS: The combined interventions produced a significant improvement of 0.14 to 0.41 standard deviation units, on average, for caregiver burden, depression, subjective well-being, perceived caregiver satisfaction, ability/knowledge, and care receiver symptoms. Intervention effects were larger for increasing caregivers' ability/knowledge than for caregiver burden and depression. Psychoeducational and psychotherapeutic interventions showed the most consistent short-term effects on all outcome measures. Intervention effects for dementia caregivers were smaller than those for other groups. The number of sessions, the setting, care receiver age, caregiver age, gender, type of caregiver-care receiver relationship (spouse vs adult child), initial burden, and study characteristics moderated the observed effects. IMPLICATIONS: Caregiver interventions are effective, but some interventions have primarily domain-specific effects rather than global effects. The differences between intervention types and moderators suggest ways of optimizing interventions.

Low back pain interventions at the workplace: a systematic literature review.

OBJECTIVE: To assess the effect of controlled workplace interventions on low back pain (LBP) through a review of controlled studies. The rising costs of employees with LBP have resulted in an abundance of offers to society and organizations of interventions to prevent and/or treat the problem. Little is known of the effect of the different interventions. METHODS: A systematic literature search based on the inclusion criteria: controlled trial, work setting and assessment of at least one of the four main outcome measures: sick leave; costs; new episodes of LBP; and pain. Effect of the interventions was reported for the four main outcome measures. RESULTS: Thirty-one publications from 28 interventions were found to comply with the inclusion criteria. Exercise interventions to prevent LBP among employees and interventions to treat employees with LBP have documented an effect on sick leave, costs and new episodes of LBP. Multidisciplinary interventions have documented an effect on the level of pain. CONCLUSIONS: The results show that there is good reason to be careful when considering interventions aiming to prevent LBP among employees. Of all the workplace interventions only exercise and the comprehensive multidisciplinary and treatment interventions have a documented effect on LBP. There is a need for studies employing good methodology.
